Inventor: MIKOL MARK CHARLES
IPC: B31B19/90
Filed: 2000-07-20
Abstract: A method and apparatus for providing a slider-equipped zipper on a pouch in a form/fill/seal operation. In the preferred embodiment of the invention, a foldable slider is employed, and is shifted from an open configuration t:o a closed configuration for installation on zipper strips on the pouch. Stops are preferably provided at the ends of the zipper strips by application of heat and pressure to form a boss on one side and a corresponding recess on the other, without requiring additional material. A hermetic peelable seal preferably is provided beneath the zipper strips. The slider preferably.is applied to the zipper strips immediately before or immediately after filling, or immediately after formation of the peelable seal. Means may be provided to shift the position of the slider to close the zipper. The slider may include means to secure it in place by a mechanical locking mechanism such as a snap fit engagement, or the slider may be welded in closed position by application of heat, or by ultrasonic welding. A vacuum engagement mechanism may be employed to separate 'the walls of the pouch to a predetermined position relative to ones another while positioning and closing the slider.

Title: Piezoelectric motor
Inventor: LAVRINENKO V YACHESLAV V
IPC: H02N2/12
Filed: 2000-08-03
Abstract: A piezoelectric motor having a stator and a rotor. The stator and the rotor are in mechanical contact with one another along at least one cylindrical friction surface by means of curved, elastic and longitudinally elongated pusher plates, the pusher plates being held against the friction surface at a first end of the pusher plates, and arranged at an angle to the friction surface. A piezoelectric element is connected to either the rotor or the stator. The piezoelectric element has electrodes placed on opposing surfaces of the piezoelectric element, and is connectable to an alternating current source via the electrodes for providing longitudinal oscillations in the piezoelectric element. A first ring plate and a second ring plate are arranged on opposite sides of the piezoelectric element, so that at least a portion of surfaces of the piezoelectric element are pressed against surfaces of the first ring plate and the second ring plate, respectively, by a clamping device. Longitudinal oscillations are thus transferred into the first ring plate and the second ring plate from the piezoelectric element, and at least one of the first ring plate and the second ring plate are in mechanical contact with second ends of the pusher plates.

Inventor: TSURUMI TAKAFUMI
IPC: G01R31/36
Filed: 2000-10-04
Abstract: The present invention provides a battery voltage measuring device capable of immediately detecting a breakage in the voltage measuring line in  a battery voltage measuring device that detects the battery voltage. In blocks formed by connecting a plurality of secondary batteries in series, voltage sensors that detect the voltage of each block are respectively provided. In addition, before these voltage sensors noise filters are provided, and in addition, a measuring line breakage detecting resistor for detecting a breakage in the voltage measuring line is connected in parallel to each block. In a battery voltage measuring device having this type of structure, in the case that the voltage measuring line Q is broken, the voltage values V1 and V2 detected by the voltage sensors 20-1 and 20-2 become voltage values that accompany the resistance ratio of the measuring line breakage detecting resistors 60-1 and  60-2. Thereby, the voltage sensor detects a voltage that is not normally detected, and as a result, it becomes possible to immediately detect the breakage in t he voltage measuring line.

Title: Highly available cluster virtual disk system
Inventor: ZHENG XIAOYAN
IPC: G06F11/14
Filed: 1999-05-07
Abstract: A cluster implements a virtual disk system that provides each node of the cluster access to each storage device of the cluster. The virtual disk system provides high availability such that a storage device may be accessed and data access requests are reliably completed even in the presence of a failure. To ensure consistent mapping and file permission data among the nodes, data are stored in a highly available cluster database. Because the cluster database provides consistent data to the nodes even in the presence of a failure, each node will have consistent mapping and file permission data. A cluster transport interface is provided that establishes links between the nodes and manages the links. Messages received by the cluster transports interface are conveyed to the destination node via one or more links. The configuration of a cluster may be modified during operation. Prior to modifying the configuration, a reconfiguration procedure suspends data access requests and waits for pending data access requests to complete. The reconfiguration is performed and the mapping is modified to reflect the new configuration. The node then updates the internal representation of the mapping and resumes issuing data access requests.

Title: Optical and programmable fiber optic wavelength add/drop system
Inventor: CAO SIMON X F
IPC: H04B10/29
Filed: 1999-06-04
Abstract: An optical and programmable wavelength add/drop system for optical networks is provided. It includes the providing of a first optical signal on the first optical loop as a plurality of wavelengths, each wavelength residing on a separate path, such that the providing occurs in the optical domain; the reflecting of any of the plurality of wavelengths; the dropping of any of the plurality of wavelengths from the first optical loop into the second optical loop and for the adding of corresponding wavelengths from the second optical loop into the first optical loop, such that the dropping and adding occurs in the optical domain; and the combining of the reflected wavelengths and the added wavelengths into a second signal. With the add/drop system in accordance with the present invention, dispersion compensation, signal amplification, and gain equalization involved in the providing of the plurality of wavelength, as well as the switching function involved in the dropping and adding of wavelengths, may be performed without the need to convert the signal from the optical domain to the electrical domain and then back to the optical domain, rendering the add/drop system simpler and less costly to implement than conventional systems. The present invention has the added advantages of being capable of broadcasting and the monitoring of the adding and dropping of wavelengths individually. The programmable nature of the present invention reduces the required number of dense wavelength division mulitplexers, and its modular design allows flexibility in upgrades to more complex systems.

Title: Navigation system
Inventor: UPPARAPALLI KARUNANIDHI
IPC: G08G1/0968
Filed: 1999-06-04
Abstract: A route exclusion list system permits the user to designate certain roads or areas that a navigation system should avoid when planning a route between a beginning point and a destination point. The route exclusion list system generally includes a database of road segments and a cost associated with the road segments, such as estimated time of travel across that road segment or estimated length of travel across that road segment. A display displays a map having a plurality of the road segments. A user input device permits a user to encircle and select displayed road segments. The cost associated with each selected road segment is increased thereby making it unlikely that the navigation system will use any of the selected road segments when determining a route between the beginning point and the destination point. The system can be operated independently of the navigation system and the increase in cost for each road segment can be associated with a specific period of time.

Abstract: In the field of retail displays there is a need for improvements to vertical, tiered displays primarily intended for laminar articles.      A modular display (10) includes upper (11) and lower (12) modules connected to one another. Each module has an upstanding wall (13, 16) and is of L-shaped cross section. The upstanding wall (16) of each lower module 12 is secured to the protruding wall 914) of the upper module (11) below the upper edge of the wall (16). The upstanding walls (13, 16) are thus in use spaced from one another to define an open ended receptacle.      The lower end of an upper module (11) and an upper part of lower module (12) have mutually engageable connector parts for connecting the modules together. This avoids the need for connector parts engageable with the free, upper edge of a wall (13, 16).
